Why does sugar dissolves very slowly in cold water and not in hot water? as we all know, sugar gets dissolved faster in hot water isn't it? what is the reason for this..anyone here?

I think sugar has a low melt point. Hot water would melt it.

Sugar has a low melting point...! taht's it? no other things to explain heer and i think chemistry students will explain such things better isn't it? all others will have confusion over this and maynot be ina position toalso give correct answers here... Anyway's, thanks for responding

I think that is something related to chemistry. When the temperature of the water increase, it make both the sugar and water molecules vibrate more rapidly, that is, increase their molecular kinetic energy. For a substance that dissolve in water, it forms hydrogen bonds with water molecules. The more the molecular kinetic energy, the more the chance to initiate this interaction, that is, more sugar can be dissolved in water when the temperature increase. I learnt that from my chemistry lesson, I hope this can help you! ;-)

Hm..yes, definitely chemistry students will answer quite fatser and looks a bit tricky for other's isn't it? and i think the way you explained this you might be an chemistry student is it? you have explained nicely here and thanks for that and it will be helpfull for others for sure Anyway's, thanks for responding
